I have a AMD X3 720 CPU with an aftermarket CPU fan and heatsink and my motherboard is the ASUS M4A78 Plus. However I can't seem to go past 3.4GHz or my system crashes on the OCCT test(bsod's). I have come to conclude that it has to be a problem with my Vcore voltage because it's set on auto, the problem is that I don't know how to adjust the voltage... so if anyone has experience with this please respond. Also, what should I get my hyperthreading ghz to? For example if it was overclocked at 3.6GHz should I just leave it on auto or on 1GHz? 1.5 GHz? etc. Thanks!
